Consider the following regarding solid waste management planning 1. Waste generation rate is an important parameter in designing waste management systems. 2. Population growth influences future waste management requirements. 3. Waste composition analysis is unnecessary in planning disposal facilities. Which of the above statements are correct?
- A1 and 2 onlyCorrect
- B2 and 3 only
- C1 and 3 only
- D1, 2 and 3
Solution
Concept
Solid Waste Management Planning
Formula
N/A
Step-by-step solution
1. Examine each statement regarding solid waste management planning. 2. Note that generation rate (Statement 1) and population growth (Statement 2) are critical parameters, whereas waste composition analysis is essential (making Statement 3 false). 3. Select Option A as the correct choice.
Explanation
Statement 1 is correct because knowing how much waste is generated helps in properly sizing equipment and facilities. Statement 2 is correct because as the population grows, the volume of waste increases, affecting future planning needs. Statement 3 is incorrect because understanding waste composition is essential to determine the right disposal or recycling methods. Therefore, only statements 1 and 2 are correct.
Shortcut
To remember key factors in Solid Waste Management Planning, use the rule "GPC = Generation, Population, Composition": - Generation Rate: Essential for sizing equipment and system capacity. - Population Growth: Crucial for estimating future demand and requirements. - Composition Analysis: Always NECESSARY (never unnecessary) to choose proper treatment and disposal methods.
Common mistake
A common mistake is selecting Option D by overlooking the word "unnecessary" in Statement 3. Students often assume that waste composition analysis is optional, whereas knowing the exact physical and chemical composition of waste is essential to choose appropriate disposal and treatment methods like composting, incineration, or landfilling.
Correct answer: A) 1 and 2 only
